Abstract
(EN)
[Problem] To provide an endoscope that makes it difficult for fluorescence acquisition to be blocked by a liquid. [Solution] An endoscope 2 comprises an excitation light source 22a for emitting excitation light, an objective lens L1 for receiving fluorescence produced as a result of the reception of the excitation light by a sentinel lymph node SLN, and a cylindrical body 244 for holding the objective lens L1. The objective lens L1 is disposed inside the cylindrical body 244 within a central portion of the cylindrical body 244 (for example, given a length L of the cylindrical body, a region between L/3 and 2L/3 from the end of the cylindrical body 244 on the sentinel lymph node SLN side). Additionally, the endoscope 2 comprises a collimating lens L3 for collimating the excitation light.

Le problème décrit par la présente invention est de fournir un endoscope qui rend difficile le blocage de l'acquisition de fluorescence par un liquide. La solution selon L'invention porte sur un endoscope 2 qui comprend une source de lumière d'excitation 22a pour émettre une lumière d'excitation, une lentille d'objectif L1 pour recevoir la fluorescence produite suite à la réception de la lumière d'excitation par un ganglion lymphatique sentinelle SLN, et un corps cylindrique 244 pour porter la lentille d'objectif L1. La lentille d'objectif L1 est disposée à l'intérieur du corps cylindrique 244 à l'intérieur d'une partie centrale du corps cylindrique 244 (par exemple, étant donné une longueur L du corps cylindrique, une région entre L/3 et 2L/3 à partir de l'extrémité du corps cylindrique 244 sur le côté du ganglion lymphatique sentinelle SLN). De plus, l'endoscope 2 comprend une lentille de collimation L3 pour collimater la lumière d'excitation.

【課題】蛍光の取得が、体液により妨げられにくい内視鏡を提供する。 【解決手段】内視鏡2が、励起光を発生する励起光源22aと、センチネルリンパ節SLNが励起光を受けることにより生じる蛍光を受ける対物レンズL1と、対物レンズL1を保持する筒状体244とを備える。対物レンズL1は、筒状体244の内部の、筒状体244の中央部分(例えば、筒状体の長さをLとしたとき、筒状体244のセンチネルリンパ節SLN側の端部からL/3以上2L/3以下の領域)に配置されている。また、内視鏡2は、励起光をコリメートするコリメートレンズL3を備える。
